Patient‐controlled tissue collection for genetic testing after early pregnancy loss, a pilot study

Abstract Objective

To determine how frequently and effectively products of conception can be obtained among women pursuing medical management of early pregnancy loss.


This pilot study was conducted to assess products of conception recovery outcomes for participants opting for medical management compared to women opting for surgical aspiration A tissue‐collection kit was provided to women opting for medical management. Outcomes measures included successful collection of products of conception, quantity and integrity of DNA, and participant satisfaction with the process.


Tissue was collected from 19 of 22 participants in the medical management group (84%) and 39 participants (100%) in the surgical management group (p = 0.02). DNA yield and integrity were similar among both groups (p = 0.03 and p = 0.003, respectively). Participants in the medical group reported a high comfort level with the kit and the process of tissue collection.


Medical management of a missed abortion followed by patient controlled collection of products of conception for subsequent cytogenetic analysis is well‐tolerated and highly effective. This methodology may reduce the need for surgical management, empower women to have more agency in their medical decisions, and increase access to genetic testing.
